Ratings and Reviews

Great RPN Calculator

Bumping genius

I have always used RPN calculators and could not use the standard x+y=z calculator that comes with the iPhone.
Now I can use my iPhone for numbers again. Great product. Apple should have it as an option to their puny app.

Low quality calculator


This app has a clean feel and nice presentation, but is seriously lacking in the calculation department. It seems to calculate with 32 bit integers and doesn't have any overflow protection, making any sort of scientific calculation next to impossible. If you're looking for a clean RPN, you should look elsewhere.
